CROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims priority from U.S. provisional application No. 60/335,196 filed Oct. 31, 2001.

TECHNICAL FIELD

[0002] The present invention relates to posts, and post systems, particularly composite wood posts and post systems.

BACKGROUND OF THE INVENTION

[0003] Fence and railing systems that employ posts are well known. For example, such systems are often used as perimeter demarcations for property and for protection of persons on decks, balconies and the like, to prevent them from falling off.

[0004] Wood products have been one of the primary sources and choices of materials for such systems. It is a relatively easy material to work with when constructing a structure such as a fence or railing system. Wood can be readily notched, grooved or cut using conventional tools such as saws or drills. It is also relatively easy to attach one piece of wood to another using such fasteners as nails or screws.

[0005] Wood is one of the materials of choice when building a fence or railing system, as standard size and shape posts can be easily shaped and attached to supporting members and to other building members such as rail or fence members.

[0006] However, wood is becoming scarce and expensive. Also, untreated wood has a susceptibility to rot, particularly when used in wet environments It is also susceptible to damage by pest infestation. The treatment of wood with preservatives, however, has drawbacks, including possible environmental concerns.

[0007] Alternate construction materials are known which can be used in certain building applications. For example, vinyl siding is now well known. Also, composite materials are becoming more popular, including composite wood materials made from the combination of a suitable resin and wood particles, flakes, fibers or the like. For example, it is known to use composite wood material in producing decking. However, in some applications these materials are not as easy to work with as wood. In particular, using a composite material in the construction of a fencing or railing system is relatively difficult because of the need to have posts, which can be readily adapted to one of several applications. For example, when building a railing system for a deck, it is typically necessary to firmly secure a series of posts to an underlying supporting substructure, such as joists, at several locations and in several orientations. Posts are usually needed at the corners of the deck as well as at intermediate positions along the deck To accomplish this, the posts may need to be configured in one of several different shapes. A standard piece of wood (eg. 2×4 or 4×4 piece of lumber) can readily be modified with standard workplace tools to form a connection portion of suitable configuration. This is in part because such standard pieces of wood are solid in cross section and thus select pieces of wood can readily be removed to form a connecting portion or connecting slot.

[0008] With posts made from composite materials, particularly composite wood materials, shaping a piece of material for a particular application is more difficult and time consuming. In part, this is because cutting through composite materials such as composite wood is much more difficult than cutting through wood. More importantly, composite members are not created with solid cross sections, one reason being because of the difficulty of forming such members with conventional techniques. Without a solid piece of material to work with, creating a connecting portion to connect a composite member to another member is relatively difficult.

[0009] Accordingly there is a need for a composite post that is not a solid piece of material, but which is of such a configuration that it can be easily adapted for use in a variety of different construction situations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0069] With reference to FIGS. 1 and 1a to 1 e, a post 10 of width W, depth D and length L, has a top end 10 a and a bottom end 10 b. Post 10 is formed with elongated channels comprising corner channels 12, intermediate channels 14 and a middle channel 16. Each channel is defined by a series longitudinally extending channel walls or web members. The channel walls are all integrally formed with each channel 12, 14 and 16 sharing more than one channel wall with another channel Thus, all the channels 12, 14 and 16 are positioned adjacent to at least two channels through common wall members. In a preferred configuration, each of the corner channels 12, have walls that provide for a channel that has an outer perimeter that is substantially square in its transverse cross section shape. Intermediate channels 14 preferably have wall members that provide a channel that is greater in width than in depth, thus providing a rectangular shaped channel in cross section. This results in a middle channel 16, which is generally square in shape but larger than corner channels 12 (FIGS. 1b and 1 e). As will appreciated from the disclosure herein, variations are possible from this preferred configuration of the nine channels arranged in a three by three channel configuration.

[0070] Post 10 could possibly be made from composites of plastics, and fibers including wood, elastomers, ceramics and glass. Such-composite materials are quite suitable as these materials can be extruded or pultruded to a desired configuration for post 10 using generally known extrusion or pultrusion techniques.

[0071] One of the most advantageous composites for post 10 is to make it from a composite wood material. Such a product can be made, for example, by combining wood fragments such as wood flakes, strands, particles, chips and fibers with a resin, particularly a thermoplastic resin, and then extruding the mixture through an extruding die, and allowing the extruded product to fully set. Examples of suitable resins include polyethylene and polypropylene. Some examples of a composite wood materials and equipment and methods that could be adapted to make a post 10 are disclosed in U.S. Pat. No. 6,153,293to Dahl et al., U.S. Pat. No. 5,516,472 to Laver and U.S. Pat. No. 5,088,910 to Gosforth et al. the contents of each, being hereby incorporated herein by reference.

[0072] Although post 10 could be used without any adaptations being made to it, it is contemplated that in most cases, the shape of post 10 will have a modified shape when put to use. The initial configuration of post 10 has been designed so that it is versatile and can be easily modified on site in numerous different ways to meet a particular construction situation. The modification to post 10 takes place by selectively removing part of one or more channel walls to provide an opening and slot. The slot and opening can then receive part of another building member, and the post can then be firmly connected to the other building member with conventional fasteners, such as nails, screws or the like. Selected portions of the channel walls can be removed by conventional construction tools, such as for example, reciprocating or circular saws.

[0073] By way of example, in FIGS. 2a-2 f, a post 110 is shown in which a post 10 has been adapted to a first configuration. Post 110 has an opening 120 made in it transversely through the outer and inner walls of one set of opposed intermediate channels 114 a and 114 b, and walls of middle channel 116. This provides a slot 121 with inner side channel walls, and slot 121 passes through post 110. The opening 120 is made from the bottom end 110 b of post 110 toward top end 110 a. As is evident in FIG. 2g, post 110 can, for example, be fitted to a supporting joist 140, which is received into slot 121. Post 110 can then be secured to supporting joist 140 with conventional fastening devices providing a secure connection between post 110 and joist 140. As many pieces of conventional lumber (such as 2 ×4, 2×6 and 2×8 members) are approximately 1.5 inches wide, the width w1 (FIG. 2a) of slot 121 is preferably sized to snugly accommodate the width of such a piece of lumber.

[0074] In FIGS. 3a-3 f, a post 210 is shown which is a post 10 adapted to a second configuration. Like post 119, post 210 has a first opening 220 a made in it transversely through outer and inner walls of one set of opposed intermediate channels 214 a and walls of middle channel 216 a. This provides a slot 221 a with side channel walls (one of which has an opening or break in it). Slot 221 a passes straight through post 210. The opening 220 a for slots 221 a is made from bottom end 110 b part way towards top end 110 a. A second opening 220 b is made in post 210 to provide a second slot 221 b at right angles to slot 220 a through walls of one intermediate channel 214 b. The combination of slots 221 a and 221 b provide a combined slot that is T-shaped. As is evident from FIG. 3g, post 210 can be fitted at the intersection of supporting joist 240 and supporting joist 242 from the end of post 210. This T-joint of supporting joists 240, 242 is received into slots 221 a, 222 b. Post 210 can then be secured to supporting joists 240, 242 with conventional fastening devices and/or the like, providing a secure connection between post 210 and joists 240, 242. Again, it is preferable that width W2 of the slots 221 a, 221 b throughout be just wide enough to snugly receive the width of a standard 2×4, 2×6 or 2×8 piece of lumber which has a width of about 1.5 inches.

[0075] In FIGS. 4a-4 f, a post 310 is shown which is a post 10 adapted to a third configuration. Post 310 has had a first slot or opening 320 a made in it transversely through the outer and inner walls of one channel 314 a, the inner wall of which is a shared wall of the middle channel 316 a, from bottom end 310 b part way to top end 310 a. A second opening 320 b is made at right angles to slot 320 a through outer and inner walls of one channel 314 b. This provides a continuous L-shaped slot 321 a, 321 b as illustrated in FIGS. 4f and 4 g. Post 310 can thus be fitted to an end of post 310 to the L-shaped intersection of supporting joist 340 and supporting joist 342. This L-joint of supporting joists 340, 342 is received into L-shaped slot 321 a, 321 b. Post 310 can then be secured to supporting joists 240, 242 with conventional fastening devices and/or the like providing a secure connection between post 310 and joists 340, 342.

[0076] Alternatively, or in addition to modifying post 10 to be secured to supporting members as depicted in FIGS. 2g, 3 g and 4 g, post 10 can be modified in other ways to be secured to other building members For example, FIGS. 5 to 5 k illustrate other possible configurations that can be readily formed from post 10 shown in FIG. 1a, and thus are suitable for use in other building situations.

[0077] It should be noted That in each case when the opening is made in some of the walls of one or more channels to form a slot, by removal of a portion of a channel wall, the slot or slots are defined by inner channel walls that provide side walls for the slots. These slot sidewalls help to stabilize any building member That is received into the slot.

[0078] In FIGS. 5 and 5a, a post 410 is shown having a first slot 420 formed at one end of post 410 by removal of one outer wall of channel 414 a (FIG. 5a) a part way from end 410 a. A second slot 420 b is formed by removal of an additional part of the same outer wall of channel 414 a at a location between slot 420 a and the second end 410 b of post 410. Thus, slots 420 a and 420 b can both accommodate building members such as ends of railing members.

[0079] Post 510 in FIGS. 5b and 5 c bas the same configuration as post 410 except that slots 420 a and 420 b are bot extended within post into and through the second opposite inner wall of channel 514 a into channel 516. This permits building members to be received further into post 510.

[0080] Post 610 in FIGS. 5d and 5 e is the same as post 510 except that slots 620 a and 620 b extend completely through post 610—in particular through outer and inner walls of channel 614 a, 616 and 614 c. Parts of building members can be received in slots 620 a, 620 b, passing completely through post 610. Thus a portion of a building member that is not an end can be securely attached to post 610 through slots 620 a and 620 b. Alternatively, each of the slots can receive an end portion of a building member at each or the two slot openings.

[0081] Post 710 shown in FIGS. 5f and 5 g has two end slots 720 a and 720 b oriented at right angles to each other and two intermediate slots 720 c and 720 d also oriented at right angles to each other. Slots 720 a and 720 c are formed by removing the outer wall of channel 714 a along parts of its length. Slots 720 b and 720 d are formed by removing the outer wall of channel 714 b along parts of its length and each are suitable for receiving for example an end portion of a building member

[0082] Post 810 shown in FIGS. 5h and 5 i has two sets of slots; each set comprising four slots. The first set of slots 820 a-820 d is located at an end 810 a. The second set of slots 820 e-820 h is located between the first set of slots 820 a-820 d and end 810 b. Each of the slots is formed by removing a part of one of the outer walls of channels 814 a-814 d. Each of the slots is configured to receive for example, an end portion of a building member.

[0083] Post 910 illustrated in FIGS. 5j and 5 k is substantially a combination of post 410 and post 610. Slots 920 a and 920 c are the same as slots 620 a and 620 b, and form a passageway completely through post 910 Slots 920 b and 920 d on the other hand are formed only by the lack of part of outer channel wall in channel 914 c.

[0084] In FIG. 51, a series of posts 630, 730 and 830 (each made from a post 10) are shown in an arrangement whereby they can be connected to a supporting joist structure generally designated 840, a series of medial rail members 740 and a series of upper rail members 640.

[0085] With reference to FIG. 8, a further configuration to which a post 10 can be adapted is shown. In this configuration, post 1010 has a pair of ledges 1020 and 1021 on each side of a medial portion 1019. As shown in FIG. 9, post 1010 can be employed to support joist or beam members 1040 which themselves are interconnected to a middle joist or beam member 1042. Post 1010 can be appropriately sized so members 1040 could be, for example, standard 2×8 or 2×10 lumber.

[0086] As shown in FIGS. 6 and 7, two posts 1010 a and 1010 b are shown supporting members 1040 and 1042.

[0087] In use, a post 10 is provided which may be any one of several standard lengths. As the post is constructed from several channels, each channel formed with channel walls that for a composite wood material are preferably in the range of about 5 to 7 millimeters in thickness. However, the wall thickness can be altered for specific applications. A post constructed in such a manner can relatively easily by cut using standard construction tools such as reciprocating saws, circular saws or the like.

[0088] The foregoing demonstrates the versatility of the composite post described herein. With one standard cross sectional configuration (e.g. post 10) being supplied to a construction site, a worker can take the standard post and easily modify it to suit a particular construction situation. It will however be appreciated by persons skilled in the art the limits of load bearing capacity of such posts is dependent upon the composite material selected among other factors.

[0089] The load bearing capacity of post 10 can, however, be increased, by the use of reinforcing elements, as illustrated in FIGS. 10 to 12. It has been recognized that the compressive strength of composite wood material is relatively high compared to its tensile strength. To increase the overall strength of a post 1210 (FIGS. 10 and 11) one or more of channels 1214, 1214, and 1216 can have a strengthening element 1233 inserted therein. It is preferred in most applications that the elements 1233 are received in corner channels 1212 or center channel 1216. Strengthening elements can be selected from a wide variety or materials having good tensile strength properties such as steel, aluminum, fiber glass. concrete and even solid wood. Metals are a preferred type of material and in many applications tubular steel tubing is preferred to provide the required reinforcement.

[0090] The dimensions of post 1210, including the size of channels 1212 and 1216, including the respective wall thickness can be chosen such standard 1 inch by 1 inch tubing can be received in channels 1212 and/or standard 1.5 by 1.5 inch tubing can be received in channels 1216.

[0091] In most applications it is not necessary to affix the elements 1233 inside the channels of a composite wood post 1210. However, there is likely to be some indirect connection between the post 1210 and at least some of the elements 1233 by virtue of the connections that are made between the post and other structural members (see for example FIGS. 12 and 13).

[0092] In addition to providing overall increased strength performance of the post 1210, strengthening elements also can be particularly useful in providing a strong connection location for post 1210 to be secured to other structural members. In the absence of a strengthening element 1233, securing connectors such as bolts through the channel walls of a post, can cause channel walls to be loaded beyond their load bearing capacity at the connection locations The channel walls might be crushed or otherwise damaged, if for example bolts must be highly tightened in making a connection to an underlying supporting substructure. As illustrated in FIGS. 12 and 13, bolts 1244 pass through a pair of opposite channels 1211, their respective strengthening elements 1233 and a joist 1240. It will be appreciated That nuts 1255 can be tightened much further without risking the collapse of the channel walls or channels 1212.

[0093] It should be noted that although in the arrangement of FIG. 12, elements 1233 are employed in both corner channels 1212 and center channel 1216, the element in channel 1216 will run only to the top of joist 1240.

[0094] Posts 1210 could be provided for use with elements 1233 already placed into one or more of the channels. However, it is preferred that one or more posts and one of more strengthening elements be provided separately (in one embodiment as a kit), such that de elements can be used as needed in each post in each particular application.

[0095] Further variations are contemplated within the scope of the invention, which is defined by the claims following hereafter. By way of example, it is not necessary that the post be configured with just nine channels arranged in a free by three channel configuration.
